12279964 divided by 636 
We want to figure out the number of times 12279964 can be divided by 636.

On to step 1:
The number 636 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 636

Let's proceed to step 2:
The number 636 fits into 12 0 times, leaving a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 636

Step 3:
The number 636 fits into 122 0 times, leaving a remainder of 122.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 122, we end up with 122.
Take the next digit (7) from the dividend and append it to 122, then repeat: 1227 / 636

Advancing to step 4:
The number 636 fits into 1227 1 times, leaving a remainder of 591.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 636 from 1227 leaves us with 591.
Take the next digit (9) from the dividend and append it to 591, then repeat: 5919 / 636

Moving on to step 5:
The number 636 fits into 5919 9 times, leaving a remainder of 195.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 5724 from 5919 and we're left with 195.
Append the next digit (9) from the dividend to 195 and continue with: 1959 / 636

Let's proceed to step 6:
636 can be fit into 1959 3 times, resulting in a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 193.0
The remainder is 51 after subtracting 1908 from 1959.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 636

Moving on to step 7:
636 can be fit into 516 0 times, resulting in a remainder of 516.
Use 0 as the next digit of our solution. 
Result so far: 1930.0
If we subtract 0 from 516, we get 516.
Grab the next digit (4) from the dividend, add it to 516, then carry on: 5164 / 636

Step 8:
5164 divided by 636 is 8 with a remainder of 76.
The number 8 becomes the next digit in our result. 
Result so far: 19308.0
Subtract 5088 from 5164 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 9:
The number 636 fits into 760 1 times, leaving a remainder of 124.
Use 1 as the next digit of our solution. 
Result so far: 19308.1
Subtract 636 from 760 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 10:
The number 636 fits into 1240 1 times, leaving a remainder of 604.
Use 1 as the next digit of our solution. 
Result so far: 19308.11
The remainder is 604 after subtracting 636 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

In conclusion, the division gives 19308.11 with a balance of 0.604.
